Interpretive Summary:

Technical Abstract: In California cruciferous crop production, diamondback moth (Plutella xylostella) is the most challenging pest to manage. Recently, this pest has become more difficult to manage in many areas of California. A number of factors may be driving these trends, but growing issues with insecticide resistance appear to play a role with insecticides used as the primary tool. In prior years, work by AZ researchers confirmed that resistance was high for a number of active ingredients at least in specific areas and that this resistance was higher typically than that seen in the AZ desert region. We conducted bioassays with a several insecticides and with a number of populations to clarify the scope of resistance. We found variability in resistance/susceptibility across the state. This information will be critical to compel growers to more rigorously consider resistance management and to help the industry adapt management to retain the efficacy of currently registered tools.
